"Tracks Of The New York City Subway" book by PETER DOUGHERTY (2016 edition).

Tracks of the New York City Subway, as its name implies, is a 153 page book containing depictions of every main line and yard track (including track numbers) in the entire New York City subway system--all 750+ miles of track and 468 stations of it! A 42-page introduction gives the reader a brief history of the system, a primer on subway signaling (including a colour insert of the most commonly-encountered signs and signals), details on chainage distances, towers, power generation/distribution and a detailed list of abandoned stations.
